Hawkeye’s digs seem perhaps a little too subdued for my tastes, however I can definitely understand why Marvel would want to turn down the guy’s purple quotient; as much like Jem, in the comics it is truly outrageous.

Truly, Truly, Truly Outrageous!

On a side note, Iron Man’s design appears to have been altered since Iron Man 2, as evidenced by the gray patches on his collar.

Though it may just be an artist’s flub, the shape of the glow on his chest emblem looks more round than triangular to me; leading me to assume that either:

A): Tony Stark decided to reshape his new element core into a circle for aesthetic purposes.

B): Severely inebriated and desperate for a way show the world how fat his cock is, Tony Stark decided to outfit his newest armor with one of his old and HIGHLY TOXIC palladium cores.

C): I’m wrong, and his chest emblem is in fact triangular.

or D): The poster artist isn’t as OCD as the average comic fan and/or hasn’t seen Iron Man 2.

My vote would go to option A, though if you’re going by some of the comics, option B is equally plausible.

Option C is of course a statistical impossibility, and was only suggested in jest.
